RE: calling RPGLE program from Java

[Colin Williams <colin.williams@xxxxxxxxxxxx>]

One way to do this is to change the error handling in your RPG program so
that if it gets an error, 
it passes back an error message as a parameter, rather than just falling
over with a message wait.

You could use the *PSSR subroutine to achieve this, but that doesn't really
help if your RPG program is calling other programs.

Another option, is rather than calling the program directly, you create a
batch process on the 400 that you communicate with via dataqueues. Then you
send your request on one dataqueue, and wait for a specified timeout period
for a response on another dataqueue. If you don't get your request within
the given time, you flag that as an error to the user.

But with threads you could achieve a similar result.

Subject: calling RPGLE program from Java


Hi
I have been working on a web project where we call
RPLGE programs from java, the problem we face is when
there is an error on AS400 and the AS400 job goes to
message wait, there is no way the web user can be
communicated, 
has anyone designed a way to tackle this issue, 
what i am planning to write a program using threads,
where one program will start a thread which will call
the RPG program and other thread will monitor this
program
Has anyone done this successfully before, or is there
any other better way of doing it


Ashish
